Karnaugh maps
In the previous topic, you learnt to simplify Boolean expressions using de Morgan’s laws and Boolean algebra. In this topic, an alternate approach to simplify a Boolean expression is explained. Karnaugh mapping is a graphical representation of a Boolean expression. This method is easier and faster to simplify Boolean expressions. Boolean expression with up to 4 variables shall be solved using this method. Beyond 4 variables, we need computer programs to solve the expressions.
This A Level Computer Science module introduces Karnaugh maps to your students, explaining:
- Simplifying Boolean expressions with 2, 3 and 4 variables using Karnaugh maps
